Below in conjunction with accompanying drawing, the technical scheme in this utility model embodiment is described in detail.
As shown in Figure 1, this utility model has disclosed a kind of hip joint passive activity auxiliary device, comprise support 6, lower limb holder 7, pulley 5, draught line 4, pulley 5 is arranged on support 6, draught line 4 comprises two free ends, be respectively the first free end 41 and the second free end 42, the first free end 41 is traction end, the second free end 42 is connected with lower limb holder 7, lower limb holder 7 hangs on pulley 5 by draught line 4, in lower limb holder 7, be provided with angular transducer, pulley 5 is auto lock pulley, auto lock pulley comprises motor 21, retaining mechanism 11, motor 21 drives retaining mechanism 11 to make locking action to the second free end 42 of draught line 4.When use, only need be to 4 one downward pull strengths of draught line, lower limb holder 7 upwards rises under the traction of draught line 4, thereby drives the lower limb being held in lower limb holder 7 to produce certain angle, to implement rehabilitation training.Owing to being provided with angular transducer in lower limb holder 7, in the time that lower limb holder 7 reaches default angle, angular transducer sends signal, user can further adopt mode manually or automatically that the second free end 42 of draught line 4 is stuck in to retaining mechanism 11, with the lengthwise position of this accurate Convenient table holder 7, thereby help patient to control training angle, patient's rehabilitation training is played to positive role.Meanwhile, because retaining mechanism 11 produces locking effect to the second free end 42 of draught line 4, easy and simple to handle laborsaving.
Particularly, as shown in Figure 2, the outer setting of pulley 5 has pulley shell 12, pulley shell 12 is surrounded on the outer wall of pulley 5, the bottom of pulley shell 12 is provided with cardo ring 10, cardo ring 10 is arranged on pulley shell 12 with retaining mechanism 11 and lays respectively at the both sides of pulley 5 longitudinal centre lines, and the first free end 41 of draught line 4 is through cardo ring 10.By cardo ring 10 is set, while patient being lied on a bed use the hip joint passive activity auxiliary device that discloses of this utility model to do rehabilitation training, needn't the worry lead of draught line 4, does involving of any direction to draught line 4 and can play draw to lower limb holder 7.
Incorporated by reference to Fig. 3, retaining mechanism 11 comprises locking teeth fixture 16, locking teeth movable piece 17, cam 19, locking teeth fixture 16, locking teeth movable piece 17 are arranged at respectively on pulley shell 12 independently, the gap of the second free end 42 of draught line 4 through locking teeth fixture 16 and locking teeth movable piece 17, cam 19 is arranged on pulley shell 12 and near locking teeth movable piece 17, cam 19 promotes locking teeth movable piece 17 and engages with locking teeth fixture 16 under the driving of motor 21.In actual use, in order to be cheaper than the flexible reset of locking teeth movable piece 17, can on pulley shell 12, set up back-moving spring 15.
Further, lower limb holder 7 adopts the holder of memory foam lower limb.The use of memory foam lower limb holder can strengthen patient's comfort, prevents pressure ulcer.
The first free end 41 of draught line 4 is provided with draw ring 3, is convenient to patient and uses.
As showing of Fig. 1, support 6 is ∏ shape, and support 6 is combined by adjustable spiral tight loop 8 by multiple support bars 61.In use, can be according to using height and the width that need to regulate whole support 6.
The bottom of support 6 is provided with the carrier base 9 for supporting bracket 6.Carrier base 9 can adopt tee T or pawl type, mainly, in order to resist the side power while manually pulling draw ring 3, increases the stability of whole device.
The hip joint passive activity auxiliary device that this utility model discloses, before use, first mounting bracket 6, is put in tailstock correct position, utilizes adjustable spiral tight loop 8 to be adjusted to proper height.When use, patient lies low on bed, need the shank of training to be fixed on lower limb holder 7 places, patient is adjusted to suitable position, arm grasps draw ring 3, utilize remote controller 2 to complete training angle initialization to device, arm draws downwards, draught line 4 completes the action of raising to shank by pulley 5, when the signal of passing back when the lower limb holder 7 of embedded angular transducer reaches angle initialization value, send locking order by the electrical control processing module of control chamber 1, motor 21 turns an angle, make cam 19 push locking teeth movable piece 17, complete the locked action of the clamping of draught line 4, realize and determined angle control, now patient's shank has reached maximum set value.When patient discharges draw ring 3 and completes downward action, the position of release controlled cam 19 and is returned to by motor 21, and locking movable piece 17 completes reset under the pushing of back-moving spring 15, and pull rope Shu Huifu freely-movable state, completes the downward traction of shank.So repeatedly, patient can the adjustable fixed angle training of execution cycle property.
The hip joint passive activity auxiliary device that this utility model discloses, has the following advantages:
(1) supporting structure, disassembly and assembly are convenient, when patient changes rehabilitation environment, are easy to carry.Solve patient's bulky complex, expensive of training device in the past, when use, comfort is poor and can only in institute, use can not take-home shortcoming.Height-width is adjustable, and flexible and saving space is applicable to various environment and a bed type.Arranging of carrier base increased the stability of installing;
(2) angular transducer and auto lock pulley are rationally set, can the angle in the time carrying out leg training accurately control patient, realize patient, family members and medical worker tripartite the controlled of hip joint range of activity examined.Make accurately concrete understanding Rehabilitation process of medical personnel, facilitate patient and family members to grasp training points for attention, ensure that patient's safety is taken exercise;
(3) pulley, draught line realize bed and weak patients also can the early stage hip and knee passive exercise of participating actively, liberated and saved nursing staff and caretaker's part labour force.Reduce traditional difficulty and danger of carrying out self-service hip joint passive exercise with towel or gauze;
(4) taken into full account patient's comfort level, whole device only lower limb holder part contacts with patient, and adopts memory foam, not only comfortable, also can prevent the pressure ulcer of heel;
(5) take up room littlely, after installing, needn't dismantle at every turn, facilitate patient need repeatedly train every day, do not hinder the comings and goings of patient's bed rest period, very convenient.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use this utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, this utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
